use and efficient in action, and which can be manufactured and sold at areasonablerIhe invention also proposes a resilient tire shoe, and aplurality of individual tube sections therein for its pneumaticinflation accomplishing partial collapsing only, upon puncturing of someof the tube sections. It is also proposed to provide a means for holdingeach of the tube sections in relative posi- 2b tions to each other todistribute the possibility of puncture evenly7 to the diiferent`sectionsso that one of the sections is not unduly mutilated. f

For further comprehension of the invention, and of the objects andadvantages y thereof, reference will be had to the follow-l ingdescription and accompanying drawings, and to the appended claims inwhich the various novel features of the invention are V moreparticularly set forth.

The vehicle tire consists of a resilient tire shoe 10, and a. pluralityof individual tube sections 11 within the. tireshoe 10 for its 50pneumatic iniation accomplishing partial collapsing only, uponpuncturing of some ofthe tube sections. The tire shoe 10 is ofconventional construction and is shown engaged upon a wheel rim 12. Thetube sections 11 are shown adjacent each other and each one constitutinga complete circle. .In transversev section of the tire,the tube sectionsdivide it into adjacent longitudinal chambers. Threetube sections havebeeniillustrated but anv desiredl number may be used. A tire "V valve 13is shown arran ed for the simultaneous inflation of all of, the tubesections.

his arrangement provides equal internal pressures.

The tire valve 13 consists of a transverse 65 head forming portion 14-and a stem portion 15. For each of the inner tube sections, a projection16 is arranged upon the head forming portion of the tire valve and anindividual air passage 17 connects with, this projection 70 and extendscompletely thru the stem por- Y tion 15. The ends of the passages 1'7are provided with Valves as described in the above mentioned copend'ingapplication.

The projections 16 terminate in head por- 75 hollow member and forcesthe clamp plate 8,5k

firmlyV against the tube section.

The means for holding each ofthe tube sec'` tions in relative positionsto each other to distribute the possibility of puncture evenly to thediEerent tube sections so that oneof the sections is not undulymutilated consists ofbaiiie strips 25 integral with the tire shoe 10 andarranged longitudinally in a complete circle within the hollowof theshoe.

These baffle strips divide the treadof the tire shoe into transverseequal sections. Necessarily upon infiation 'of .the inner tube sections,these baliie strips hold 'the 'outer peripheries of the different tubesections' in desired spaced relations to eachother. Dur- 1Go This meansconsists of baiiie 4strips 26 arranged longitudinally Within the tireshoe l0 in a complete circle and separate from p the tire4 shoe. Each ofthe baie strips is provided with a plurality of spaced outer projections 27 slidably engaging within channel strip members 28 imbedded inthe tire shoe. Each of the outer Aprojections 27 is formed with atransverse slot'29 receiving the head 8O of a bolt 3l extending thru thetire shoe into a recess 32 upon the periphery of the tire shoe. A nut 33engages each of the bolts and in -tight condition normally holds thebaile strips in adjusted positions.

rI he nuts 33 may be loosened and the battle strips transverselyadjusted for dividino the interior of the tire shoe differently. poninliation of the tube sections, they are limited in positions asdetermined by the bafle strips. if' In this condition the tire isnormally used.` vIn the event ofa puncture of one of the tubesections,the nuts 31 are removed so that one or the other of the baile strips isloose depending upon which of the tube sections have been punctnred.Immediately the tube sections stlll containing air, expand for fillingup the space caused by the'delation of the Vpunctured tube sections. Inthis condition the tire may be used until a service station is reachedfor repairing. The baiile strips also'bend to restrict the diierent tubesections to proper inflations, that is,

said ba'le strips and tire shoe for adjustably supportm means me udingholding nuts located in rethe baie strips, said coacting cesses in thetire shoe so as to be reachable from the exterior of the tire shoe.

2. A vehicle tire, comprising a resilient tire shoe, a plurality ofindividual tube sectlons therem, and means for holding each of the tubesections in relative positions to each other to distribute thepossibility.. of

uncture evenly to the different sections so that one of the sections isnot unduly mutilated, said means comprising longitudinal circular baiestrips between said tube sections and adjustably mounted within the'tireshoe, and coacting means on the bathe strips and tire shoe for adjustingthe baiile strips from the exterior of the tire. In testimony whereof wehave ailixed our signatures.
